Well. since we're pirates, the hat would be whatever kind of hat that strikes your fancy, that you could pillage. I'd like to get a really big tricorn with lots of gold trim and feathers. You can always go with a bandanna tied around your head, too.
Over on the main page, I think I've seen some knitted or crocheted FSM hats. But those aren't much good in the summer.
